1. Evolution: Proving it
Studies in genetics and molecular biology, fields unknown in Darwin's time, have explained the occurrence of the hereditary variations that are essential to natural selection. ... Moreover, scientists can perform experiments to study evolution in real time, just as experiments are used to observe dynamic processes in physics, chemistry, and other branches of biology. To study evolution in action, scientists use organisms like bacteria and fruit flies that reproduce quickly, so they can see changes that require many generations. The extensive evidence in support of both fact and theory o...
